l and useful ImprovementsinSpring-Wheels,

of which lthe following is a specification. My invention relates to flexible or spring wheels for wagons, motors and other vehicles; and it has for its object to provide a durable wheel of this tye of simple construction and capable o vbeing manufactured at a reasonable price. l

In the accompanying drawings-Figure 1 is a view of suilicient of a vehicle wheel to illustrate how' my invention is applied thereto, the parts uniting a spoke w1th a wheel rim being` v is a central lsectional view -through the parts uniting a spoke with the wheel rim, and

' taken on a plane at right angles to that of the section of Fig. 1. Fig. 3 is a side elevation of the parts illustrated in Fig. 2.

In the drawings, A designates the hub of the wheel, and B the spokes radiating therefrom, these being of any usual or preferred construction.

C designates the rim ofthe Wheel which, in the drawings, is re resented as 'being compcsed of a wooden elly c, a. metal rim c outside of the felly, and a solid rubber tire c outsidethe metal rim.

The end of each spoke is reduced to form a tenon b on which is placed a cap D preferably of :met-al. This cap consists essen- Ltially'of a plunger section d into which ex- 'y tends the tenon b, and surrounding the tenon a shell or casing d and preferably extending somewhat beyond the end thereof. Between the shell d and the plunger finis e cap D can be formed of a single unitary piece of metal or of several pieces properly united, as may` be preferred, and its exte- ,agal

rior shape may be suited to the shape and style of the spoke upon which it is secured. Preferably the shell d is ofabout the same exterior size transversely as t e spoke. E designates a socket in which is placed the coiledl spring H that is located between the endof,l the spoke and the wheel rim. The plunger d at the end of the spoke bears st one end of the spring, while its opshown in section. Fig. 2-

posite end rests upon the bottom or end of the socket E. extends into a recess J formed therefor in the wheel rim and is supported by a bearin F seeuredto the wheel rim by bolts G an I nuts g. The socket E is provided with a pair of trunnions e, `about midway between socket, that rest in seats in the flanges or side wal pieces F. pivotally connected with the rim, the bearings F, in order to allow that free dom of movement between the spokes and rim. which is necessary in wheels of the type to which my invention be ong-s und where the spokes a slight degree. The end of the spring socket E extends into the space between the plunger d and the casing d of the cap D at the end of the spoke.

the ends of the f formed therefotr s of the bearing the rim in the manner described it will be seen that the hub of the wheel, and incidentally the body of the vehicle which thel wheelsupports, is flexible or yieldinglr sup-i ysively come below the axis of the w heel. By causing the inner end of the spring socket to enter the free space within the cap D there is formed between the two movable parts of the spoke in effect and function a part of the spoke), a closed joint that is not objectionable i1` appearance and operates to hold the two parts of the spoke in proper relation to each other. and dirt from the spring chamber within the socket. At the inner end or bottom of the space surrounding the plunger of thc cap D, into which the end of the springr prevent' objectionable shocks and jars should the'spring be sufiiciently compressed to lallow the end of the casing to reach the IIIOYeS.
